17 Now Abner had communicated with the elders of Israel, saying, Ye sought for David aforetime to be king over you; 18 and now do [it], for Jehovah has spoken of David, saying, By my servant David will I save my people Israel out of the hand of the Philistines, and out of the hand of all their enemies. 19 And Abner also spoke in the ears of Benjamin; and Abner went also to speak in the ears of David in Hebron all that seemed good to Israel, and that seemed good to the whole house of Benjamin. 20 So Abner came to David to Hebron, and twenty men with him. And David made Abner and the men that were with him a repast. 21 And Abner said to David, I will arise and go, and will gather all Israel to my lord the king, that they may make a covenant with thee, and that thou mayest reign over all that thy heart desires. And David sent Abner away; and he went in peace.

(Read 2 Samuel 3:7-21)
Many, like Abner, are not above committing base crimes, who are too proud to bear reproof, or even the suspicion of being guilty. While men go on in sin, and apparently without concern, they are often conscious that they are fighting against God. Many mean to serve their own purposes; and will betray those who trust them, when they can get any advantage. Yet the Lord serves his own designs, even by those who are thus actuated by revenge, ambition, or lust; but as they intend not to honour him, in the end they will be thrown aside with contempt. There was real generosity both to Michal and to the memory of Saul, in David's receiving the former, remembering probably how once he owed his life to her affection, and knowing that she was separated from him partly by her father's authority. Let no man set his heart on that which he is not entitled to. If any disagreement has separated husband and wife, as they expect the blessing of God, let them be reconciled, and live together in love.
